From 0eec16ce91d245044f362aaed06fc363d0842363 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Fri, 30 Jul 2021 14:33:08 +0200 Subject: fix rootless port forwarding with network dis-/connect The rootlessport forwarder requires a child IP to be set. This must be a valid ip in the container network namespace. The problem is that after a network disconnect and connect the eth0 ip changed. Therefore the packages are dropped since the source ip does no longer exists in the netns. One solution is to set the child IP to 127.0.0.1, however this is a security problem. [1] To fix this we have to recreate the ports after network connect and disconnect. To make this work the rootlessport process exposes a socket where podman network connect/disconnect connect to and send to new child IP to rootlessport. The rootlessport process will remove all ports and recreate them with the new correct child IP. Also bump rootlesskit to v0.14.3 to fix a race with RemovePort().
